Throughout this book, we've used the following typographic conventions:
Constant width
Constant width in body text indicates a language construct, such as a VB.NET statement (like For or Do While ), an enumeration, an intrinsic or user- defined constant, a structure (i.e., a user -defined type), an operator, a declaration, a directive, or an expression (like dblElapTime = Timer - dblStartTime ). Code fragments and code examples appear exclusively in constant-width text. In syntax statements and prototypes , text set in constant width indicates such language elements as the function or procedure name and any invariable elements required by the syntax.
Constant width italic
Constant width italic in body text indicates parameter names . In syntax statements or prototypes, constant width italic indicates replaceable parameters. In addition, constant width italic is used in both body text and code fragments to denote variables .
Italic
Italicized words in the text indicate intrinsic or user-defined functions and procedure names. Many system elements, such as paths and filenames, are also italicized. In addition, URLs and email address are italicized. Finally, italics are used the first time a term is used.
